उत्तर
A point has 5 as its x–coordinate and 4 as its y–coordinate. Then the coordinates of the point are given by (5, 4).
Explanation:
To denote a point in 2-D, we use two numbers viz. the x-coordinate, the y-coordinate.
In the ordered pair, the x-coordinate is written in the first slot and the y-coordinate in the second slot separated by comma.
Hence, the required point is (5, 4).

This graph shows a map of an island just off the coast of a continent. The point labelled B represents a major city on the coast. The distance between grid lines represents 1 km.
Point A represents a resort that is located 5 km East and 3 km North of Point B. The values 5 and 3 are the coordinates of Point A. The coordinates can be given as the ordered pair (5, 3), where 5 is the horizontal coordinate and 3 is the vertical coordinate.
(i) On a copy of the map, mark the point that is 3 km East and 5 km North of Point B and label it S. Is Point S in the water or on the island? Is Point S in the same place as Point A?
(ii) Mark the point that is 7 km east and 5 km north of Point B and label it C. Then mark the point that is 5 km east and 7 km north of Point B and label it D. Are Points C and D in the same place? Give the coordinates of Points C and D.
(iii) Which point is in the water, (2, 7) or (7, 2)? Mark the point which is in water on your map and label it E.
(iv) Give the coordinates of two points on the island that are exactly 2 km from Point A.

(vii) List three points on the island with a y-coordinate less than 4.
